FEED GAUGE PIN. l 3.1;-

Application filedJuly 9,

This invention relates to improvements in feed gauges for use on prmtmgpresses, and is more particularly adapted to a feed gauge pin which isto be secured'on the tympan sheet of a platen printing press.

One of the important objects ofthe pres ent invention is to provide adevice of the above mentioned character which may be readily and easilysecured on the tympan sheet to facilitate the feeding of the sheets tobe printed to the press and regulate and maintain the proper position ofthe same as the are presented to the type. r

A urther object is to provide a feed gauge pin of the above mentionedcharacter wherein the paper engaging face "of the body portion of thegauge pin is relatively broad and smooth so as to prevent the edge ofthe paper from being dented when it strikes the pin and hanging thereto.

Furthermore the pin is provided with a depending tooth which is arrangedadjacent the front smooth face of the body portion, the same beingadapted to bite into the tympan sheet and to prevent the paper fromhanging on the bottom edge of the A still further object is to provide afeed gauge pin of the above mentioned character which is simple inconstruction,inex- ,pensive, and furthermore adapted to the purposes forwhich the same is designated.

Other objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawing forming part of this specification and inwhich like numerals are employed to designate like parts throughout thesame: 7

Figure 1 is a top plan view of the feed gauge pin embodying myinvention, showing the same secured on a tympan sheet,

Fig. 2 is a bottom plan view of the gauge pin per se,

Fig. 3 is a side elevation, and

Fig. 4 is a longitudinal sectional view.

In the drawing wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 1 designates generallymy improved feed gauge pin, the same comprising the substantiallyrectangular body portion 2 which is formed of any suitable metal. Theforward edge of the body portion provides the sheet engaging face 3, thesame being very smooth.

Dependin from the bottom of the body porupwardly and extending into thebody per-- tion2 as illustrated at 7, the major portion of the pin beingdisposed rearwardly of the body along the bottom thereof and terminatesin the sharpened point 8. This point is adapted to be inserted into thetympan sheet 5 in the manner asclearly illustrated in Fig. 1 so that thetooth 4 will provide a meansfor properly positioning.-

and supporting the gauge pin on the tympan sheet of a platen press.

Also extending rearwardly from the body portion 2 of the feed gauge pinare the pressure members 9 and 10 respectively, the same being arrangedon opposite sides of the prong 6 and being also formed of any suitablewire. The rear free ends of these strands of wire are bent downwardlyand thence upwardly to provide the tympan sheet engaging feet 1.1. Thepurpose of the provision of these pressure members is to provide a meansfor forcing the feed gauge pin downwardly against the surface of thetympan sheet tending to eliminate the slipping of the feed gauge pinfrom its proper position on the tympan sheet.

The feed gauge pin is further provided with the usual paper engagingtongue 12,

the same being formed of a single or double strand of wire and extendinglongitudinally through the body portion 2 in the manner as clearlyillustrated in Figs. 1, 2 and 4 of the drawing. The rear end of thestrand of wire forming the paper engaging tongue is coiled about one ofthe pressure members as illustrated at 13 and the forward free end ofthis strand of wire projects beyond the forward smooth edge of the bodypor tion for a suitable-distance as is also shown clearly in thedrawings.

\Vhile I have shown only one of such tongues, it is to be understoodthat one or more tongues may be provided as is desired and necessary asI do not wish to limit myself to the particular number of tongues. Thepurpose of the tongueis to keep'the paper from curling up and ridingover the no I pin as frequently occurs when such a tongue is not used,

\Vith the mechanical platen press feeders now generally used, paper isfed to these gauge pins at right angles with their face and usually atgreat speed. The wide smooth face 3 of my improved gauge pin willprevent the edge of the paper from be ing dented when it strikes the pinand hanging thereto. Also the provision of the tooth t will prevent thepaper froinhanging on the bottom edge of the pin, thus eliminating agreat deal of trouble which is ordinarily experienced in register work.

The simp-licity'w-ith which my improved feed gauge pin is constructedenables the same to be readily and easily attached on the tympan sheetso that it will not become accidentally disengaged therefrom. Funt-hermore a device of the above mentioned character may be manufacturedat a very low cost and will be strong and durable.

\Vhi le I have shown the preferred embodiment of my invention, it is tobe underand arrangement of parts may be resorted to without departingfrem the spirit or and-having its front face flush with the forward edgeof the body portion, the bottom edge of the tooth being sharpened andadapted to bite into the tympa-n sheet, a prong extending along thebottom of the rear portion of the solid body, the forward end of saidprong being bent upwardly and v disposed within the body portion,therear end of the prong being pointed and extending rearwardly from the"body portion and adapted to be inserted in the tympan :sheet, pressuremembers extending rearwardly from the body portion on opposite sides ofthe prong, the rear ends of the pressure members terminatingin tympansheet engaging feet, and a tongue projecting from stood that variouschanges in the size, shape the forward end-of the solid body portion;
